Use of consultancy services

1. General

1.1. Consultancy services should be employed by either works managements

or competent authorities who do not have sufficient expertise to fulfil the tasks

required within a major hazard control system. The competent authorities should in

particular consider the use of consultants during the early stages of the development

and implementation of a major hazard control system.

1.2. Consultants at national or international level should be selected according

to their relevant field of expertise, such as chemistry, process engineering, process

control, systematic hazard analysis, environmental science, toxicology, emergency

planning or training of workers.

2. Use of consultancy services by the competent authorities

2.1. Authorities implementing a major hazard control system should preferably

employ consultants having experience with a major hazard control system

elsewhere.

2.2. Where necessary, consultancy services should be used by the competent

authorities for such tasks as:

(a) establishing a definition for major hazard installations;

(b) establishing and training a Group of Experts within the competent authorities;

(c) evaluating hazard analyses prepared by works managements;

(d) preparing off-site emergency plans;

(e) establishing a policy for siting of major hazard installations.

3. Use of consultancy services by works management

3.1. Works management should employ consultants only if its expertise or

manpower is insufficient to cope with the tasks specified by the major hazard control

system. The tasks should where possible be carried out by the works management.

3.2. Where necessary, consultancy services should be used by works

management for:

(a) carrying out the hazard analysis and preparing the safety report in close co-

operation with works management;

(b) establishing guidelines for the safe design and operation of the installation and

their application in component design, process control, operating manuals, etc.;

(c) analysing the consequences of potential accidents (e.g. dispersion of toxic

releases, blast waves, thermal radiation) by means of modelling to assess their

possible impact;

(d) establishing on-site and, where appropriate, off site emergency plans;

(e) training of workers.
